The USHL has a strong crop of defensemen eligible for the 2008 NHL Entry Draft, and Cedar Rapids RoughRiders defenseman Matt Donovan is one of them. The 6-foot-0, 190-pound blueliner is not as big as some others are, but the Oklahoman is among the USHL’s leaders in defensemen scoring as a rookie and leads the league in plus/minus just over halfway through 2007-08.
